Which is not part of a dc motor?
a. coil of wire
b. magnet
c. compass
d. brush
e. commutator

(C). Compass

Explanation:

DC motor:

The DC motor converts electrical energy to mechanical energy.

When the electric current passes through a coil placed in a magnetic field, a torque is produced which causes the coil to rotate

The parts of dc motor are as follows :

Coil of wire:

The electric current passes through a coil.

Magnet:

Coil is placed between two magnets.

Brush :

The brush carries current to the armature.

Compass :

Compass is used to detect the direction using magnetic field. Compass is not required in DC motor.

Commutator :

In a DC motor, commutator is used to reverse the direction of the armature current in the brush zone so that the torque is exerted in same direction.

Therefore,

The compass is not a part of a DC motor.

false
